Abstract

1. Apparatus for producing an optical signal in dependence upon an electric operating magnitude of an insulated cable of an energy supply network, having an electrode (20) capacitively coupled to the conductor of the cable in a fitting (11) to be attached to the end of the cable and an indicator devive (1, 2, 3), characterized in that the indicator device (1, 2, 3) comprises a multisegment liquid crystal display (1), a decoding and driver device (2) which controls the display (1) and can be connected to the electrode (20) by an input circuit (3), and in that the display (1) and decoding and driver device (2) are combined to form a unit which can be attached to the fitting (11) and thus connected to the electrode (20).
